To all whom it may concern:

Be it known that I, JOHANN C. SELL, a citizen of the United States,residing at Pryor, in the county of Mayesand State of Oklahoma, haveinvented certain newv and useful Improvements in Loading Mechanisms, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to certain improvegeneral character especiallydesigned and adapted for use in connection with'shocks, and it is anobject of the invention to provide a device of this general characterem-, bodying a sweep supported for vertical swinging movement, togetherwith novel and improved means for imparting upward movement to thesweep.

, Another object of the invention is to provide a deviceof this generalcharacter of a portable type including a sweep, together with meanswhereby the load received by the sweep may be readily and convenientlydelivered to a collecting or receiving member such as a trailing barge.

An additional object of the invention is to provide a novel and improveddevice of this general character including a sweep supportedfor'swinging movement in a vertical direction, together with powerdriven means for imparting upward movement to the sweep and whereinmeans are employed to assure the downward movement of the sweep afterdischarging its load. Furthermore, it is an object of the invention toprovide a device of this general character embodying a verticallymovable sweep, together with novel and improved means whereby thedownward movement of the sweep may be readily regulated "inaccordancewith the requirements of practice.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my im proved loadingmechanism whereby certain important advantages are attained and thedevice rendered simpler, less expensive and otherwise more convenientand advantageous for use, as will be hereinafter more fully set forth.[*1

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the tatably supported by;

better understood, I will now proceed to describe the same withreference to the accompanying drawings, wherein:

Figure 1 is a view partly in side elevation and partly in sectionillustrating a loading mechanism constructed in accordance with anembodiment of my invention, a second position of the sweep beingindicated by. dotted lines.

Figure 2 is a view partly in section and partly in top plan of thestructure as disclosed in Figure 1.

Figure 3 is a view in rear elevation of-certain of the parts comprisedin my device as herein set forth, and v Figure 21 is a fragmentary viewillustrating in detail the brak'ing mechanism herein employed. I Asdisclosed in the accompanying drawings, T denotes a portable body andpreferably a tractor and which includes a casing 1 for the shafts of therear or drive wheels D. Engaged with the opposite end portions of thecasing 1 are the rear end portions of the elongated arms 2 havingswinging movement in a vertical direction. The arms 2 are arrangedinwardly of the wheels D and eX- tend forwardly of the body ortractor Tinwardly of the front or steering wheels F and terminate in advance ofthe body or tractor when said .arms 2 are substantially horizon- .tal orin their lowermost position.

Carried by the forward end portions of the arms 2 and in advance of theportable body or tractor T is a sweep S of a conventional type adaptedto be employed in connection with shocks or the like.

Extending rearwardly from the opposite end portions of the casing 1 andinwardly of the arms 2 are the rearwardly directed beams 3 immovablewith respect to the body or tractor T and which preferably terminaterearwardly of the wheels D. The rear end portions of the beams 3 supportthe uprights 4 disposed. on a slight forward incline. Connecting theupper portions of the uprights 4: and the forward portion of the body ortractor T are the brace members 5 whereby said uprights are maintainedin a rigid position.

A transversely disposed shaft 6 is rothe rear end portions of the beams3 and t e lower portions of the uprights 4 and said shaft at a pointsubstantially midway between the uprights 4 1 the be is provided with anannular flange 7 so that the portion of the shaft 6 between the uprights4 constitutes a pair of separated winding drums.

Fixed to one end portion of the shaft 6 is a relatively large pulley 8around which is disposed a belt 9. The belt 9 extends forwardly of thebody or tractor T and is also disposed around a pulley 10 in drivenconconditions, the proper gripping action of the have requisitefrictional or said members belt 9 upon said pulley 10.

The upper'stretch of the belt 9 also passes under an idle pulley 12rotatably supported by the free end portion of an elongated arm or lever14 having its opposite end portion loosely engaged with the shaft 6 sothat said arm may be capable of vertical swinging movement.

The arm or lever 14 has rigidly connected therewith an upstanding andforwardly inclined lever 15. This lever 15 provides means wherebydownward pressure may be imposed upon the arm 14 to cause the pulley 12to tighten the belt 9 so that said belt will gripping engagement withthe pulley 8 so that the shaft 6 may be rotated in one direction at thewill of the operator:

.Rotatably supported by the upper end portions of each of the uprights 4are the pulleysl6 over which pass the flexible mem bers 17. The forwardend portions of the members 17 are secured to therear'portions of thesweep S adjacent the opposite ends thereof whi e the opposite endportions of are secured to the opposite end portions of the shaft 6 andare adapted to be wound therearound upon rotation of said shaft 6through the instrumentality ofthe belt 9. This winding of the members 17upon the shaft 6 results in an upward swinging movement of the sweep Sso that the load thereon may be delivered 01' discharged rearwardly ofthe body or tractor T and preferably within a trailing barge or wagonfragmentarily indicated by B. The upper end portions of the uprights 4are connected by a downwardly and rearwardly inclined apron 18 uponwhich the load from the sweep is initially received and which serves toassure the proper delivery of the load within the barge Just before thesweep S reaches the limit of its upward movement, the arms 2 come intocontact with the transversely disposed rod or member 19. This member 19is secured at its opposite end portions to the bolts 20 slidablydisposed through the upper portions of the uprights 4 and movable in adirection ,longitudinally of the body or tractor'T. These bolts 20extend in advance of the uprights 4 and terminate in the enlargements21.

Interposed between the enlargements 21 and the forward edges of theuprights/4 are the expansible members 22 herein disclosed as coilsprings encircling the forward end being suflicient to throw the arms 2beyond a vertical center.

As the sweep S descends and the'fiexible members 17 unwind, the shaft 6will be rotated in a direction reverse to its rotation by the belt 9. Itis of importance to regu-' late or brake this second rotation. of theshaft 6-to control the downward movement of the sweep S. As hereindisclosed, the shaft 6 has fixed thereto a disc of brake wheel 23v withwhich coacts a brake strap 24, said strap being operated in a Well knownmanner through the medium of the lever 25. By proper operation of thelever 25, the sweep S may be brought to a stop at any point during itsdownward movement or such movement may be at a speed preferred andparticularly at such speed to cause the sweep S to reach its loweredposition or come in contact with the ground without undue force orimpact.

The lever 25 "s provided with a conventional type of latch mechanism 26coacting with the rack27 so that the lever 25 may be locked in itsdesired position either to lock the sweep S in an elevated position tohold the strap 24 in such contact with the coacting disc or brake wheelto maintain the lowering movement of the sweep S at a predetermined rateof speed.

It is to be understood in practice that the body or tractor T is causedto travel forwardly with the sweep S in its lowered posivention isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled and operated, and it will alsobe obvious that my invention is susceptible of some change andmodification without departing from the principlesand spirit thereof andfor this reason I do not wishto-be understood as limiting myself to theprecise arrangement ease-re I and formation of the several parts hereinsaid arms being of shown in carrying out my invention in practice exceptas hereinafterclaimed.
